Preventing marine plastic pollution

Clean Sea Solutions’ autonomous robot and modular floating dock collect marine plastic waste and prevent the inflow of plastic to the open sea.

Marine pollution is the fastest growing environmental problem in the world, according to the UN. Approximately 10 to 20 million metric tons of plastic end up in the ocean each year, equivalent to a truckload every minute, according to the World Economic Forum. Up to 94 per cent of the plastic waste entering the ocean sinks into the seabed and breaks down into microplastic particles over time. It is critical, therefore, to prevent the inflow of plastic waste before it reaches the open sea.

Autonomous clean-up of plastic waste

In collaboration with the City of Oslo, Clean Sea Solutions is launching two innovative technologies to reduce and prevent the inflow of plastic waste into the ocean: an automous robot and a modular floating dock. The Clean Sea Robot is an autonomous, electric, floating aqua-drone that “sweeps” and collects plastic trash that has collected in coastal areas. It uses a combination of computer vision and remote sensing based on ultrasound or 3D laser scanning (LIDAR) technologies. The robot gathers trash and and stores it on board, disposes it at a dedicated docking station, and recharges for the next mission.

The Clean Sea Flexi Pod is a flexible, modular floating dock with integrated waste collection. Plastic debris flows from around the pod into internal collection pools with “waterfalls” created by electric pumps. The Pod operates independently or in combination with other collection devices.

Clean Sea Solutions has two additional products under development. The Clean Sea Flexi Bin is a solar-powered floating container that collects waste. The Clean Sea River Pod collects downstream river waste above and below the water surface.

Concrete benefits

Addressing the urgent worldwide call to reduce marine plastic pollution, Clean Sea Solutions’ technologies combine modern design, effciency and high technology.

The Clean Sea Robot and Clean Sea Flexi Pod are autonomous and can be equipped with sensors for enhanced data collection. Both are scalable and easy to maintain.

Market potential

In Western countries, marine waste management is becoming an integral part of national, regional and development policy. Demand for automated waste collection equpment is growing, particularly in the Mediterranean where significant resources have been allocated to France, Spain and Italy through the Mediterranean Action Plan. This market is estimated to increase to 10.2 per cent by 2024, compared to 8 per cent in 2018.

Africa is another priority region where 70 million metric tons of waste are generated each year, but only 10 per cent is collected. By 2025, over 160 million metric tons of waste will be generated annually, and much of it will end up in the sea due to lack of proper waste treatment.

Clean Sea Solutions has signed an agreement with the Port of Oslo and the Agency for Urban Environment of the City of Oslo and will deliver the first Clean Sea Robot to the Port of Oslo at the end of summer 2019. The company has also received funding for further development from the Norwegian Retailers Environment Fund.
